Question

What daughter product is produced when thallium–206, an isotope of thallium, undergoes beta minus (β–) decay?

Answer 1

When an isotope undergoes beta minus (β-) decay, daughter product will form as next element of periodic table, which would be Lead here with Atomic number 82.

⁸¹Tl₂₀₆ → ⁻¹e₀ + ⁸²Pb₂₀₆

In short, Your Answer would be Lead-206

Hope this helps!

Answer 2

`\left \{ {{y=206} \atop {x=82}} \right.Pb`

Step-by-step explanation:

`\left \{ {{y=206} \atop {x=81}} \right.Tl` ⇒ [tex]\left \{ {{y=206} \atop {x=82}} \right.Pb +\left \{ {{y=0} \atop {x=-1}} \right.e

when a nucleus undergo beta decay the mass number stays same while the atomic number increases by 1
